🔍 Key Concepts

• Diesel engine governing systems and how they control speed at idle • Role of the hydraulic governor and its internal adjustments in preventing speed fluctuations (hunting) • Difference between speed-setting adjustments and stability/damping adjustments in a governor

💭 Think About

• Think about which choice deals with stability of speed (preventing hunting) rather than simply changing the set idle RPM • Ask yourself: if the engine is already at the correct idle speed on average but is surging up and down, which part of the governor is meant to smooth that behavior? • Consider which action is normally used as periodic maintenance versus which is a fine adjustment to correct hunting

✅ Before You Answer

• Identify which option relates to the governor’s damping or compensation feature rather than basic speed setting or load limiting • Ask whether changing the load limit would realistically affect an engine running at no-load idle • Consider whether draining and flushing the governor is a maintenance step for contamination or a tuning adjustment for hunting
